Skipping process mapping before configuration
Configuring an ERP around assumed processes rather than mapped, verified ones is the single most common source of costly rework mid-implementation. Map the process with the people who actually run it, not just management's description of it.
Underestimating data migration
Legacy data is rarely clean. Budget real time for data cleansing and validation, and run migration rehearsals well before go-live rather than treating migration as a final-week task.
Under-investing in training and change management
An ERP that staff don't trust gets worked around with shadow spreadsheets, quietly reintroducing the exact problem the ERP was meant to solve. Training and a clear go-live support plan are not optional extras.
Frequently asked questions
Should we customize the ERP or adapt our processes to it?
Where your process is not a genuine differentiator, adapting to the ERP's standard workflow is usually cheaper and more maintainable long-term. Reserve customization for the processes that actually set your business apart.
How long should we plan for an ERP rollout?
A focused single-department rollout can take a few months; a full multi-department implementation with data migration and training commonly takes six months to a year. Phased rollouts reduce risk versus a single company-wide cutover.
